Energy Ring

There are lots of ways to show users how much battery they have, at a glance. It can be done simply by displaying a percentage, but that’s just boring. With Energy Ring, the battery level is shown around the camera lens, on phones that support this option.
 
Energy Ring has a ton of options, and the developers figured out many of the possible problems. For example, the application will hide itself when an application goes full screen. It’s also possible to determine the width of the ring down to 1 pixel, and there shouldn’t be a significant impact on the battery.
 
Users can also choose colors and the directions of movements, not to mention the fact that the app features a nice charging animation.
